Bellman Equation in Reinforcement Learning
the Bellman equation captures one profoundly simple insight: the value of being somewhere now equals the immediate reward you receive, plus the discounted value of wherever you end up next. That recursive observation, formalized by the American mathematician Richard Ernest Bellman in the early 1950s, transformed decision-making theory and quietly became the mathematical backbone of modern artificial intelligence.

Small Language Models(SLMs) in Modern AI Engineering
Large Language Models (LLMs) like GPT-5, Gemini, and Claude have demonstrated remarkable reasoning and generative capabilities. However, their scale comes with trade-offs: high latency, massive compute requirements, privacy concerns, and limited deployability on edge devices.This has led to the rise of Small Language Models (SLMs)—compact, efficient models designed to deliver strong performance under tight resource constraints.
